When I switched to vertical tabs in Firefox, the Hikcentral professional web client camera server page changed, part of the page appeared at the top, making it difficult to use and watch the camera images, and the image doesn't display properly. How can I fix this problem?

While browsing on my desktop , I am unable to open E Shram Card blog. it appears like there is an error in connection , but despite of good connection, cannot open it.

I’ve been troubleshooting a strange networking issue in Firefox that I haven’t been able to pin down, and it seems to be specific to Firefox’s network stack rather than my system or connection.

On several high-traffic sites that sit behind Cloudflare (Discord, Shopify storefronts, some SaaS dashboards), Firefox occasionally stalls during page load. The request shows up in the Network panel as pending for several seconds before finally completing. Sometimes the page partially renders and then hangs until the stalled requests finish.

A few things that make this confusing:

• The same sites load instantly in Chromium-based browsers on the same machine and network • The issue persists even in Firefox Troubleshoot Mode with extensions disabled • DNS over HTTPS on/off does not appear to change behavior • Packet captures show the TCP connection is established quickly, but some HTTP/2 streams appear to wait before data begins flowing • If I force HTTP/1.1 using a proxy for testing, the issue disappears

System details:

OS: Windows 11 Firefox: latest stable release Connection: fiber, low latency, no packet loss locally No system proxy configured

Things I’ve already tried:

• Clearing cache and site data • New Firefox profile • Disabling hardware acceleration • Testing with network.http.http2.enabled toggled • Comparing HAR logs with Chromium

One thing I noticed in the Firefox networking logs is that multiplexed streams sometimes wait behind earlier streams longer than expected, almost like there’s some internal prioritization or queue behavior happening. I’m wondering whether this could be related to HTTP/2 prioritization logic, connection coalescing, or how Firefox handles Cloudflare edge endpoints.

Has anyone seen similar behavior or knows whether there are any advanced networking prefs in about:config worth experimenting with (connection limits, HTTP/2 concurrency, etc.)?

Curious if this might be a known quirk with certain CDNs or just something unique to my environment.

This just happened, (45 minutes). When I attempt to access a page or a file, when the page comes up on screen, it is a page of numbers and symbols. How do I remove these pages??

hello, i cannot seem to find a solution online, hopefully someone can help.

i often receive emails with images attached, and most of the time people don't resize their images. you can imagine over time this all adds up in the email storage folder total size.

i dont always need to keep a 6mb image version, it can be reduced after i am done.

i would like a method to resize the received emails image attachment, to at least still have a smaller copy for refence, but not end up with a huge thunderbird email account profile (in the email received not externally saved)

preferably a one click solution, or even a routine i can run on the file system, etc. or some way to edit the received email and its attachment in program.

thanks

Today I have experienced a problem downloading new messages, bulk, trash or anything else in my mail server into thunderbird. it requires my primary password and then my regular password. I just set up my primary password so I understand why it is asking for that, but I don't understand why it is also asking for my regular password before I can get access to the mail server that I am using. the regular password was set up on 6/17/24 and until today it was working fine.

Lost my Passwords on my desktop and can't recover them through profile manager, I found them on my android phone and want to recover my passwords from there, but am worried if I try and sync to the desktop, the desktop might overwrite the passwords in the phone.

Thunderbird--All of my current year INBOX emails disappeared. I have tried repairing the folder, deleting INBOX.msf and restarting including in troubleshooting mode, reinstalled Thunderbird. None of these actions changed the situation. Is it possible to retrieve these messages?

The INBOX folder is much larger than the INBOX.msf folder, so I'm thinking the message info is in there?

I;m using Windows 10.

Ok, This is a bit of a question that seems to have many answers but none that have ever worked for me. I have in the past 12 months probably formatted my PC 4 times, and I have at least 12 profiles on Firefox nightly, not to mention the rest of the family. It's not really a problem to redo them every time, but it is just a painstaking simple process. If I could just backup the profile folder, copy it move it change it whatever, it would be nice and simple, even to transfer from one pc to another in the house, but every time I try, It fails. Copy the Userdata folder, copy the entire firefox folder, blah blah blah, never can I do it. I believe it has something to do with security that you can't just copy and the entire profile folder, but some way to backup the profiles exists surely? One that actually works. Cheers All!

I can no longer access YouTube videos (video unavailable) with Windows 10 and Firefox. However, I can access them with Google Chrome. How can I resolve this issue?

As of yesterday my Firefox browser no longer displays some screens within Amazon Prime correctly. It displays what should be images as text, which is difficult to read, unlike Microsoft Edge, which displays the Amazon webpage correctly. I am running Windows 10 with a support extension through October 2026, so could it be an update from Microsoft Windows or Mozilla Firefox that has caused the problem. Thanks for your help.

Duck duck search via Firefox has become painfully slow, although if Google search is used the speed is OK. I have cleared caches, cookies etc without any improvement. Firefox 148.0.2, Windows10. Is this a recognised current problem?

I was locked out from yahoo completely but managed to reconnect with their web client today but Thunderbird still doesn't work. my connection is POP with my ports set as: inbound.att.net 995 outbound.att.net 465 when I test the connection under settings in Thunderbird reports: Successfully established a secure connection to inbound.att.net:995. Successfully established a secure connection to outbound.att.net:465. I was at Version 146.0.1 so I upgraded to 148 with no difference
